SPRING-CUSHION CONSTRUCTION.

Application lcd February 1, '1923. Serial No. 616,250.

To all whom it may concern:

Be it known that we, SAMUEL SUEKOFF and WILLIAM W. GLEAsoN, citizens ofthe United States of America, and residents of ,t Chicago, Cook County,illinois, have invented a certain new and useful Improvement inSpring-Cushion Construction, of which the following is a specification.

The object of our invention is to provide lo a method by means of whichto economize in the fabric necessary to be used, and to also economizetime and labor in the sewing of the parts together, and. yet provide aspring cushion, or the like, which shall mainl tain the springs thereofunder compression in an upright position, isolated fromeach other byfabric.

Our invention has certain other objects in view which will more fullyappear hereno inafter, and in addition to the method to be described,consists in certain novel completed constructions which will be fullydescribed.

lin the accompanying drawings- Fig. l is a top plan view of a portion ofa continuous length 4of the fabric having thereon sewingindicatinglines.

Fig. 2 is a perspective view of thel collective spring enclosingcompartments.

Fig. 3 is 'a perspective view of a partl of one of the divisional fabricpartitions.

Fig. i is a diagrammatic view illustrating the arrangement of the sewingmachines relative to each other and to the continuous 35 length ofmarked and cut fabric, the sewing machines being indicateddiagrammatically, whereby the partition strips are sewn along the linesmarked on the continuous length of fabric.

Fig. 5 is a perspective view of a portion of the top piece with thepartitions sewn thereto.

Fig. 6 is a view similar to Fig. 4;, illustrating the position of thesewing machines by'means of which the other edges of the partitionstrips are sewn to the bottom piece and-the boxing portion of the topand bottom pieces are sewn together.

Fig. 8 is a top plan view of the cushion with top cover removed to showthe internal arrangement, and

Fig. 9 is a perspective view of a single spring retainer.

Curinvention considered broadly is the method of constructing springcushions or cushion foundations, for use in furniture, coach and motorbuilding, and comprisinga covering of burlap or like material,consisting of pieces sewn together and enclosing a plurality of springs.

More specifically the invention pertains to the method of assembling thevarious. pieces of fabric` that make up the cover, including the top,bottom and side pieces, the partition members, forming the springenclosing compartments, and the springretainers, by which the individualsprings are assembled in rows for insertion as units into the springcompartments.

The method employed in constructing the multiple collective springenclosing comto the depth or width of the cushion' to be made. Thelength of the fabric for convenience should be approximatelythreehundred yards so that a continuous length of fabric is provided ofa width equal to one dimensionl ofthe cushion to be made. As shown, twocontinuous lengths of the fabric are provided to constitute the top andbottom pieces A and B--Fig Qf-cf the cushion, which also constitute thetop and bottom of the collective spring enclosing compartments.Continuously along one face of the length of fabric, as shown in Fig. 1,continuous sewing indicating lines 2 are marked. The cutting and markingis done simultaneously by a machine in a well lknown manner. When thislength of the fabric is cut transversely to obtain the dimension of thecushion transversely to that obtained by the longitudinal cutting of thefabric, the" top and bottom pieces A and B are obtained, which are sewntogether by the seams a--, thus providing vthe boxing or sidewalls A2 ofthe cushion. Therefore, in cutting the continuous length ofthe fabric`longitudinally, it should be cut ofa width sucient to provide the topor bottom portion, plus :one-half the height of the spring under comlimipression, plus the seam allowance. 'In some instances, however, it isnecessary to provide for the tacking of the assembled springs to thewooden framework of a chair or the like, and under such conditions thecontinuous length of the fabric is cut ,thewidth or depth of the cushionplus suiiicient material to' the compartments, continuous strips are cutof the fabric of a width equal to the height of the springs undercompression plus two seam allowances.

The partition strips C are sewn to the top and bottom pieces in a mannerto be now described: Haying reference to Fig. 4, sewing machines areconventionally represented at D, the number of such machines employedcorresponding to the number of seams. These sewing machines are arrangedin echelon one behind the other in such lateral position so that theneedle bar d of each machine coincides with an indicating line 2.Inasmuch as it is impossible to distinguish the top piece from thebottom piece in the completed cushion, for purposes of description wewill refer to the continuous length to which the partition strips C arefirst sewn as the top strip, and the strip to which the remaining edgesof the partition strips are sewn as the bottom strip.4 As the cut andmarked-length of fabric is advanced, the leading sewing machine of thegroup, the needle bar of which coincides with the first indicating line,sews the continuous partition strip C (to the left) along the markedindicating line to the top strip A2, the seam beingjust inwardly fromthe edge of the strip which coincides with the marked indicating line 2,as shown in Fig. .6. In the further advancement of the top strip A, the

-neXt partition strip C yis sewn along the next indicating line to thetop strip, and so on until all of thepartition strips are sewn along theindicating lines to the top strip, as shown in Fig. 5.

The top strip A with one edge of the partition strips sewn to it maythen be inverted and the operation repeated to sew the opposite edges ofthe partition strips to the bottom strip A3, the work being done on thesame group of machines or another group of sewing machines may beprovided, as shown in Fig. 6, arranged in like manner as previouslydescribed and located beyond the first group whereby the operation ofsewing the partition strips to both top and bottom strips is continuous.When the partition strips 4are sewn to both the top and bottom strips,the overlapping portions of the top and bottom constituting the boxingor side walls A2 are sewn together, andthecovering 'rpatei'ial thuscompletedv asl shown in Fi o-complete the structure constituting themultiple collective spring enclosing compartments, the top and bottomstrips, including the partition strips, are cut transversely atintervals sutiicient to obtain the dimension of the cushion transverselyto that obtained by the longitudinal cuttin of the fabric. When this isaccomplis ed, the multiple collective spring enclosing compartments arein the form illustrated in Figs. 1, 2 and 7, with the ends of the springcompartments open.

To close the open ends of the spring com- Y partments separate stripsmay be sewn to the topand bottom pieces to form the end walls, one endof the cover being preferably closed before the springs are inserted,leaving one end of each compartment opened to admit the springs.

The springs l-l, are of the ordinary helical cylindric form, ofsubstantially the height ofv the spring compartments of the covers lt isthe practice to place the springs under initial compression beforeplacing them into the compartments, various means being adopted fordoing this. Forinstance, a row ofsprings may be placed in a jig andcompressed, the jig being inserted endwise vinto a spring compartment,and then with drawn, leaving the Springs in place, and at the same timepermitting them toexpand.

It is preferable, however, to separate the individual springs withfabric, in order to prevent their relative movement, as well as todeaden the scraping and creaking noises that would otherwise result inthe iiexing of the springs under the weight placed upon them. v

To facilitate the insertion ofthe springs into the compartments, we havedevised a method that has been found to be very satisfactory. ln thefirst place, the same fabria' cated material is used which forms thecover, this material being cut transversely into narrow strips K of awidth about one half -the diameter of the springs. Each strip K, asshown in Figure 9, is therefore f`- a short length of thecover materialshown in Figure 7, and because of its formation is conveniently termed aspring retainer. These retainers would manifestly be of the same lengthas the spring compartments of compressed andinsered ntop'cach cell orincasso compartment ot the retainer and when com` pleted, insertedendwise into each spring compartment, and anchored in place 4by lines otstitching f, passing lengthwise oit the spring compartments, through thetop piece A of the cover, the ends of the springs, and the material oithe spring retainers as shown in Figure 8. q

rllhis method of utilizing the same maf terial :tor both covers andspring retainers makes tor economy in cushion manufacture, besidesproviding a very satisfactory and servicable construction.

lt/laniiestly, certain departures may be ,permitted in the methodtherein disclosed,

without departing from the' spirit of the invention. For instance, thecovering material may be sewn in short lengths and the work done on asingle machine instead or' the gang arrangement described. 'lhecontinuons or gangmethod, however, is a matter oiE development toward ahigh state et production and etticienc and to be attained as rapidly ascon itions will permit. Y

What we claim as our invention is:

l. A method ot manufacturing spring cushions consisting ot sewing narrowtabric strips along their'side edges to top and bottom fabricl pieces,along parallel spaced lines to torni a cover member containing aplurality ot spring compartments extending the length or width oi thecushion, cutting other similarly iormed tabric. members transversely ofthe narrow strips to torm relatively narrow spring retaining members,inserting springs into said 'spring' retaining members, and insertingthe lled spring retaining members endwise into said compartments andclosing the ends oit' said compartments. l
